WebThis means cycloalkane molecules are closer on average in the liquid, and as van der Waals forces are attractive (at intermolecular separations) and their strength varies inversely with distance, the intermolecular attractions are stronger in cycloalkanes, and so the boiling point of the cycloalkanes should be higher. WebMelting/boiling points, however, has to do with the intermolecular forces between the atoms of the octane molecule. When octane changes from solid to liquid to gas, it is still octane - i.e. the carbons and hydrogens remain bonded to each other in the same way. ... Are cycloalkanes more stable than their respective straight chains, since ...

WebCycloalkanes have boiling points that are approximately 10 – 20 o C higher than the corresponding straight chain alkane. There electronegativity difference between carbon and hydrogen (2.1 vs. 1.9) is small; therefore, there is only a slight bond polarity, meaning that the only attractions between one molecule and its neighbors will be Van ... WebJun 5, 2024 · Why do Cycloalkanes have a higher boiling point?
